The Atlanta closer walked the bases loaded with one out in the 12th inning before Will Venable lined a single to give the San Diego Padres a 3-2 win over the Braves on Saturday night.

"When you go out there and throw a lot of balls and walk guys, that's what happens,' Kimbrel said. "I can't go out there and walk that many batters."

Yangervis Solarte walked to start the 12th, and Jedd Gyorko and Chris Nelson drew consecutive one-out walks. Venable followed with his game-winning single over the head of right fielder Jason Heyward to give the Padres their fourth win in five games. Atlanta extended its losing streak to five games.

Kimbrel (0-3), who normally pitches just one inning, entered the game to start the 11th.

"He has the makeup to do it but to be able to do it, it's a little different," Braves manager Fredi Gonzalez said. "It's not that simple."

The Braves loaded the bases in the top of the 12th with no outs, but Stauffer got Evan Gattis to hit into a third-to-home-to-first double play and retired Chris Johnson on a groundout.

"I think that was the game right there," Stauffer said. "I think that kind of put the stamp on it."

Atlanta tied the game at 2 in the eighth on Heyward's single, a walk and Johnson's RBI single.

Trailing 1-0, the Padres went ahead in the seventh. Rene Rivera led off with a single, was sacrificed to second and scored on Solarte's two-out single. After San Diego loaded the bases, Jordan Whalden relieved Ervin Santana and threw a wild pitch that allowed Solarte to score for a 2-1 lead.

Santana allowed two runs and six hits in 6 2-3 innings with six strikeouts and four walks.

San Diego's Tommy Medica had two more hits, including a second-inning single that gave him hits in six consecutive at-bats. Medica went 5 for 5 on Friday with two two-run homers, setting career highs for hits, RBIs and runs with four.

TRAINER'S ROOM

Braves: Heyward was back in the starting lineup after missing four games with a strained back. "It's been four days, but it seems like it's been a month," Gonzalez said.

Padres: Right-hander Andrew Cashner (right shoulder soreness) will make a rehab start Friday with Single-A Lake Elsinore. ... Left fielder Carlos Quentin, on the 15-day DL (left knee soreness), will get a second opinion in Los Angeles sometime in the coming week. ... Catcher Yasmani Grandal (fluid in right knee) was out of the starting lineup for the third straight game.

ON DECK

Braves: Right-hander Aaron Harang (9-6, 3.43 ERA) pitches in the series finale at Petco Park where he resurrected his career by going 14-7 with a 3.64 ERA in 2011, his only season with San Diego.

Padres: Right-hander Tyson Ross (10-10, 2.60) has thrown eight consecutive games of six or more innings while allowing two or fewer runs, the longest streak in the NL and second in the majors to Seattle's Felix Hernandez, who has done it 14 straight games.

PASSING OF BRAVES BROADCAST LEGEND

Former Braves broadcaster Pete Van Wieren, 69, passed away Saturday morning after a long bout with cancer. "One of the nicest people I ever met," Gonzalez said about Van Wieren, who broadcast Braves games for 33 years.

PRACTICE IS OVERRATED

Despite having little practice, the Padres ground crew did a commendable job in working the seldom-used tarp before the game at Petco Park, where a light drizzle hit in the afternoon. The Padres have had just 16 rainouts in 46 seasons, and only one in Petco's 10-year history

FINALLY OVER .500

The Padres went over the .500 mark at home (1,821-1,820) for the first time since Aug. 28, 2010.
